Ostriches are huge, flightless birds, native to Africa. But they can run very fast, at over 40 mph, making them the fastest of all running birds in the world. They also have the largest eye all animals living on land. In fact an ostrich’s eye, which is almost the size of a billiard ball, is bigger than its brain. Its eye takes up much of the space in its skull.
The ostrich needs large eyes to adapt to its terrestrial lifestyle. On sighting any danger, it doesn’t hide its head in the sand as is popularly believed. Thanks to the long neck and legs which make it stand upto the height of 9 ft, it enjoys an excellent view over the grassland and bush. Its large eyes with a high number of photoreceptor cells combined with the sheer size of the image from the lens help the ostrich to see phenomenal details of the predators even from great distances. So, if it sees something trying to sneak upon it then it will run away as fast as it can with its big, long powerful legs.
